| Abstract: | The effect of excitation current on MF5602 negative temperature coefficient(NTC) thermistors produced with the new process was investigated in the temperature rang from 20 K to 50 K.The results could be concluded that the excitation current influence on the measuring accuracy of MF5602 negative temperature coefficient(NTC) thermistors produced with the new process was larger than old process,and the current source of different precisions should be selected according to the need of measuring accuracy. |
